Think of your staircase or hallway. Light switch at one en lights in the middle, light switch at the other end. Trace the wires carefully in the diagram so you can connect them to the proper locations.
It should also help in understanding the . Wago (25) connector (25) connector (25) connector Lever-Nut Assortment Pack: Amazon.
How to wire 3-way switches using NM (Romex) cable with wiring diagrams included.
Tutorial: How 3-way and 4-way switch circuits work.
Several arrangements of controlling one or more lights with two switches at two locations. Here are several variations of using - way switches to control lights from two locations. A three - way switch has four different screw terminals on its body: The green screw is always for the ground wire (this is the bare copper or green insulated wire ).

Connect the ground wire to the green screw. It is good to know how to troubleshoot light switches and switch wiring. The figure below shows the simplest possible configuration: In this diagram, the black wire is hot. That is, it carries the 120-volt AC current. For more information on household . The most basic circuit, with only two wires at the switch.
This arrangement would typically be used in conduit, and uses two wires between each switch.
